Connecting cable
Connecting cables are necessary for connecting the
individual basic units with their current measuring modules
and, if required, with their expansion modules or operator
panels. They are available in various versions and lengths
(ribbon cable 0.025 m, 0.1 m, 0.5 m; round cable 2.0 m). The
total length of all connecting cables must not exceed 3 m per
system!
Contactor
Electromagnetically actuated low voltage switch with only
one rest position, which is not manually operated and can
make, carry or break currents under normal circuit conditions
including operating overload conditions.
A contact system comprises main and auxiliary contacts (NC
contacts and NO contacts). Main contacts can switch
currents of several hundred amps (depending on the size of
the contactor), while auxiliary contacts are only suitable for
low currents.
Control functions
Control functions (e.g. direct starters, reversing starters) are
used for controlling load feeders. They are characterized by
the following important features:
• Monitoring the switch-on/switch-off process (no current
flows in the main circuit without the ON command)
• Monitoring the OFF state (no current flows in the main
circuit without the ON command)
• Monitoring the ON status
• Tripping if a fault occurs.
Control stations
Control stations are places from which control commands are
issued to the motor. The "Control Stations" function block is
used for administration, switching and prioritization of these
different control stations. SIMOCODE pro allows the parallel
administration of up to four different control stations.
Dependent on the control function, up to 5 different control
commands can be transmitted from every control station to
SIMOCODE pro.
• Local control, in the direct vicinity of the motor. Control
commands via pushbuttons.
• PLC/PCS, switching commands are issued by the
automation system (remote).
• PC, control commands are issued via an operator control
station or via PROFIBUS DPV1 with the SIMOCODE ES
software.
• Operator panel/operator panel with display, control
commands are issued via the buttons of the operator
panel/operator panel with display in the switchgear cabinet
door.
